Answer:
no
Step-by-step explanation:
10² + 24² ≠ 28²
The older brother was born three years before the young one, which means that their age will always differ by 3. Don't be fooled by the fact that, in this particular year, the age of the older brother is exactly twice the age of the younger! This is not a property that will be carried on with the years: for example, next years bother A will be 4 and brother B will be 7, and 4 is not half of 7!
So, since the property that remains constant is the three year gap, when brother B (the older one) will be 60 years old, brother A will be 3 years younger, as always, which means that he will be 57.
We need to use simple division to solve the problem. The number of students in the painting class this month is 14.
It is said that each student pays $12 for class and $28 for materials. The total amount paid by each student can be calculated by adding both of them. We know that the total amount this month is $560, we need to find the number of students in the class. Let us consider the number of students in the class to be x, and multiply the total amount per student to x and equate it to 560.
(12+28)x=560
40x=560
x=560/40=14
Therefore the number of students in the painting class is 14.
